Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618646, here are decompositions:

7 + 8618639 = 8618646
53 + 8618593 = 8618646
79 + 8618567 = 8618646
89 + 8618557 = 8618646
163 + 8618483 = 8618646
167 + 8618479 = 8618646
233 + 8618413 = 8618646
269 + 8618377 = 8618646

Showing the first eight; more decompositions exist.
